"First, inspired by Teacher Jiang Xiaoping's Road Widening Flow, I temporarily used Road Narrowing Flow!"

"Road Narrowing Flow, as the name suggests, means narrowing the road and lowering its road classification!"

"For example, everyone, please look at the intersection of Zhongshan Street and Renmin Road. Going southeast and southwest from this intersection, after traveling through roughly two more intersections, there are two elementary schools!"

The contest staff were quick to catch on and promptly projected the corresponding road sections from the sand table onto the big screen.

Song He paused before continuing:

"Under normal circumstances, drivers can choose to go straight at the intersection or turn left or right. But in reality, most people will go straight, which leads to frequent accidents and traffic jams at the intersection of Renmin Road and Jianshe Road one kilometer ahead!"

"My approach is to narrow the road in the middle section of Renmin Road and modify the traffic lights and lanes at the intersection. The straight-through green light will be very short, while the left- and right-turn green lights will last much longer, diverting traffic to both sides in advance!"

"On the sand table simulation, the effect of narrowing the road isn't obvious, because once the small cars detect that they can continue ahead, they'll still take the shortest route forward. But in reality, when drivers see a narrowed section, they'll instinctively avoid it and take the unobstructed main road instead, making the diversion effect more significant!"

"Therefore, once this design is implemented in reality, the congestion rate will drop even further!"

"According to my estimate, the final congestion rate under my plan can reach approximately 7.5%!" Song He made a shocking declaration.

"Sato Masanobu's plan takes the opposite approach to mine. He chose to widen the congested sections. Although that would be
